Analysis of fire services coverage in Spain
Previous analysis of the locations of fire stations in Spain and the extent of the areas they cover revealed significant deficiencies with regard to the proportion of communities who would not receive fire service intervention ... -
Applications of sensing for disease detection
The potential loss of world crop production from the effect of pests, including weeds, animal pests, pathogens and viruses has been quantifed as around 40%. In addition to the economic threat, plant diseases could have ... -
Bulk optical of potato flesh in the 500 – 1900 nm range
In this study, the optical properties of potato flesh tissue were estimated using double-integrating sphere (DIS) measurements combined with an inverse adding-doubling (IAD) light propagation model. Total reflectance, ... -
Classification of beef longissimus thoracis muscle tenderness using hyperspectral imaging and chemometrics
Nowadays, the meat industry requires non-destructive, sustainable, and rapid methods that can provide objective and accurate quality assessment with little human intervention. Therefore, the present research aimed to ... -
Combination of spectral and textural features of hyperspectral imaging for the authentication of the diet supplied to fattening cattle
This study explored the potential of hyperspectral imaging in the near infrared region (NIR-HSI) as a non-destructive and rapid tool to discriminate among two beef fattening diets. For that purpose, a feeding trial was ... -
Detection of minced lamb and beef fraud using NIR spectroscopy
The aim of this work was to investigate the feasibility of near-infrared spectroscopy (NIRS), combined with chemometric techniques, to detect fraud in minced lamb and beef mixed with other types of meats. For this, 40 ... -
Evaluation of mechanical tomato harvesting using wireless sensors
The harvesting of processing tomatoes is fully mechanised and it is well known that during harvest, fruits are subjected to mechanical stress causing physical injuries, including skin punctures, pulp and cell rupture. Some ... -
Evaluation of near-infrared hyperspectral imaging for the assessment of potato processing aptitude
The potato (Solanum tuberosum L.) is the world's fifth most important staple food with high socioeconomic relevance. Several potato cultivars obtained by selection and crossbreeding are currently on the market. This diversity ... -
Evaluation of risk factors in fatal accidents in agriculture
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2010) Artículo / ArtikuluaEn el ámbito agrario se producen anualmente muchos accidentes mortales, no siendo todos ellos registrados oficialmente como accidentes laborales. El objetivo de esta investigación es comparar los datos reales y oficiales ... -
Exploring the potential of hyperspectral imaging to detect Esca disease complex in asymptomatic grapevine leaves
Precise and reliable identification of specific plant diseases is a challenge within precision agriculture nowadays. This is the case of esca, a complex grapevine trunk disease, that represents a major threat to modern ... -
Fatal tractor accidents in the agricultural sector in Spain during the past decade
Currently, there is a discrepancy between the number of occupational accidents in the agricultural sector reported by Spanish governmental sources and those actually occurring in general. This is mainly due to the official ... -
Hyperspectral imaging to assess the presence of powdery mildew (Erysiphe necator) in cv. Carignan Noir grapevine bunches
Powdery mildew is a worldwide major fungal disease for grapevine, which adversely affects both crop yield and produce quality. Disease identification is based on visible signs of a pathogen once the plant has already been ... -
Hyperspectral imaging using notions from type-2 fuzzy sets
Fuzzy set theory has developed a prolific armamentarium of mathematical tools for each of the topics that has fallen within its scope. One of such topics is data comparison, for which a range of operators has been presented ... -
Imágenes hiperespectrales para el estudio de la respuesta a la deficiencia de nitrógeno de distintos cultivares de patata
(Sociedad Española de Ciencias Hortícolas, 2021) Contribución a congreso / Biltzarrerako ekarpenaEl cambio climático es uno de los mayores retos de la agricultura moderna. El aumento del rendimiento de los cultivos en el futuro sólo será posible si pueden hacer frente a las consecuencias del cambio climático causado ... -
Imágenes hiperespectrales para el estudio de la respuesta a los estreses abióticos (deficiencia de riego y abonado) de distintos cultivares de patata
El objetivo de este trabajo fue evaluar el potencial de las imágenes hiperespectrales para clasificar tubérculos sometidos a estreses abióticos controlados. -
Mathematical models to describe the volumetric shrinkage rate of red beans during drying
The present study aimed to determine the volumetric shrinkage rate of bean (Phaseolus vulgaris L.) seeds during air-drying under different conditions of air, temperature and relative humidity, and to adjust several ... -
A multi-year analysis of traffic accidents involving agricultural tractors
The agricultural sector in Spain is responsible for a high rate of accidents every year, and many of them are traffic accidents. Tractors are a relatively rare sight on roads, meaning that the incidence of accidents involving ... -
Near-infrared spectroscopy and hyperspectral imaging for non-destructive quality inspection of potatoes
La patata (Solanum tuberosum L.) es uno de los cultivos más importantes en el mundo, ocupando el quinto puesto en términos de producción. España es uno de los países europeos con mayor producción y consumo de estos tubérculos. ... -
Non-destructive detection of blackspot in potatoes by Vis-NIR and SWIR hyperspectral imaging
Blackspot is a subsurface potato damage resulting from impacts during harvesting. This type of bruising represents substantial economic losses every year. As the tubers do not show external symptoms, bruise detection in ... -
Phytochemicals determination and classification in purple and red fleshed potato tubers by analytical methods and near infrared spectroscopy
BACKGROUND: Over the last two decades, the attractive colours and shapes of pigmented tubers and the increasing concern about the relationship between nutrition and health have contributed to the expansion of their ...
